STATIC RELAY.

SPEGIFIGATION forming part of Letters Patent No. 657,221, dated September 4, 1900.

Application filed May 20,1899. Renewed March 1'7, 1900. Serial No. 9,109- (No model.)

To aZZ whom it may concern.-

Be it known that I, ISIDOR KITSEE, of the city and county-of Philadelphia, State of Pennsylvania, have invented certain new 5 and useful Improvements in Static Relays,

of which the following is a specification.

My invention relates to an improvement in static relays.

The object of my invention is to produce a no device useful for relaying rapidly-recurring or alternating currents or currents generated with the aid of friction-machines.

Referring to the drawings, Figure l is a vertical section through an electroscope provided with my arrangement. Fig. 2 is a section through the tube on the line 2 2 of Fig. 1.

Fig. 3 is a diagram showing the electrical connection.

A is the non-conducting base; B, the nonzo conducting tube, preferably made of glass;

0, the cap, and D the conducting-rod, provided with the conducting-ball d, the conducting lower portion (1, and the conductingleaves 01 b l) are two conductors placed in juxtaposition to the leaves 01 c c are wires connecting the conductors b and b to the binding-posts e and e.

To the binding-post e is connectedthe wire f, connected to the battery F, the other pole of which is connected through the wire f with the sounder or other receiving instrument S. The wire f connects the free terminal of the sounder to the binding-post e. This circuit is grounded at G through wire f The modus operandz' of actuating this device is as follows: Normally if all parts of the instruments are at zero the leaves d d are converged. The battery-circuit there- 0 fore, including the sounder, is open; but as soon as the atmosphere surrounding the con. ducting-ball d is charged with electricity, or a conductor carrying the current of electricity is either in proximity to said ball or is touch 4 5 ing the same, the leaves will separate and will touch the conducting-uprights b 12', thereby closing the local circuit, including the battery F, which in turn will actuate the sounder. In some cases, such as space telegraphy, it

.is preferred to have the air in the tube B partially exhausted. The static or high-tension impulses of electricity having caused the diversion of the conducting-leaves will pass through the conductors Z) Z) to the ground G and will establish the zero condition necessary for the convergence of the leaves, thereby opening thelocal circuit.

Having now described my invention, what I claim as new, anddesire to secure byLetters Patent, is-= 6o 1. In electricity a relay consisting of con ducting-leaves in juxtaposition to conductors connected with the interposition of abattery to an electromagnetic device and to the ground, said conducting-leaves being provided with means for connecting the same to one terminal of the receiving-circuit.

2. In electricity a relay consisting substantially of an electroscope provided with conductors in juxtaposition to the conductingleaves, said conductors being electrically connected to a local circuit containing a generator of electricity and an electromagnetic device said circuit being also connected to the ground.

3. In electricity, a relay consisting of conducting foil or leaves-inserted in a partiallyexhausted tube, said leaves being provided with means to connect the same with the terminal of a circuit, in combination with con-- ductors placed in juxtaposition to said foil or leaves, the conductors being connected to a local circuit including a battery and electromagnetic device.

In testimony whereof I sign my name, in the presence of two subscribing witnesses, this 12th day of May, A. D. 1899.

ISIDOR KITSEE.
